Well now this makes me wonder...

I've yet to establish a ponic grow, me answering "5.5 - 6.1" is born from all the material I've read, and that range being the most frequently found.
But I've also read examples of a slighter higher range like bliss seems to prefer. And I should add...certainly looks to have good results happening in a current grow.

So...is it something in a difference between indica & stativa? Environment? Grower preference/response?

This bound for hydro mind wants to know.
